Immanuel Kant showed us that facts only become facts within us, as part of a representation of the world constructed by our minds. Later we would discover that in addition to the filters of our senses, facts were also shaped by the knowledge and systems of values of those who perceived them. From this facts became increasingly seen as a human construction, subjective and distant from the original impression of being absolute and static entities. The old phrase “Against facts there are no arguments” lost more and more meaning. And the way you or I perceive the world is, and always will be, unique. As unique as a face.
